parted"fron1 the counter ,20. ST his counter shaft 20 is. mounted in suitable. bearings 21 which are provided upon-a crossbar '22 secured upon the lied l, asvclearly shown and additional hearings'a nd supports for.

sziid counter shaft are .providedby 'stnndards or supporting arms 23 which are vsecured to the extremities of-the rearlaxle l7 and extend ug iartlly theref'romto theextrcmities of tllfift'illltil shat. Sprocket pinions 14 end are provided uponithe counter shaft adj. cent the ends-thereolinnd sprocket chains 26 pagg around the aid pinions and the sprocket wheels 19 arranged immediately in rear of-the respective pinions to transmit the motion of the counter shaft to the rear axle -17 and thereby cause the traction wheels to travel over the ground. The sprocket pinion 24 is fixed upon the countershaft while the pinion 25 is loose thereon and is provided upon its inner face with a clutch hub or member 27 having a ratcheted inner edge. This clutch hub or member 27 is normally engaged by a mating clutch member 28 which is slidably fitted upon the counter shaft but constrained to rotate therewith and held toward the clutch hub or member 27 by a spring 29 coiled upon the counter shaft between the said clutch member 28 and the adjacent bearing 21. I prefer to employ a collar 30 to receive the thrust of the inner end of the spring 29 and have illustrated such collar in the drawings, but it is to be understood that the omission of the said collar will involve no departure from my invention, The collar may be adjusted longitudinally of the shaft so that the tension of the spring may beregulated and maintained. 'The clutch member 28 is constructed with an annular groove in which fits a portion of a lever 31 having its front end fulcrumed upon a bracket 32 projecting laterally from the cross bar or member 22 of the frame as shown, the rear end of the said lever 31 being connected by a link 32 with a hand lever 33 which is fulcrumed at its front end upon the said cross bar 22 and extends rearwardly to a point adjacent the operators seat 14. When it is desired to turn the carriage to the left the hand lever 33 is shifted so as to withdraw the clutch member 38 from its engagement with the clutch hub or member 27 and thereby permit the left hand traction wheel to remain approximately stationary while the carriage is turning. l/Vhen the carriage is to be turned to the right the left-hand traction wheel will travel at a greater speed than the counter shaft and the ratcheted face of the clutch hub 27 will -automatically ride over and be disengaged from the mating face of the clutch member 28, as will be readily understood.

' A sprocket wheel 34 is mounted upon the counter shaft 20 adjacent the right hand end thereof and a sprocket chain is trained around the said sprocket wheel and a sprocket pinion 36 fixed upon the crank shaft 37 of an engine 38 which is mounted upon the bed 1. This engine will preferably be of the internal combustion type although any other form of motor may be employed and the detail construction and arrangement-o? 'the parts of the said motor constitute no part of my present invention. The motor is therefore illustrated in conventional manner only and it will be understood that it may be mounted upon the bed 1 in a manner most convenient to the user. The sprocket wheel 34 is fitted loosely upon the counter shaft and is adapted to be locked thereto by a friction clutch indicated generally at 39 and which may be of any wellknown type. The slidable member of this friction clutch is controlled by a hand lever 40 which is fulcrumed upon the frame of the carriage in advance of the counter shaft and extends rearwardly to a point adjacent the operators seat. By manipulating the hand lever 40 the clutch may be caused to lock the sprocket wheel to the counter shaft or release it from said shaft so that the carriage may be caused to'travel or may be permitted to remain at rest without requiring the stoppage of the motor as is often desirable.

To compensate for the wear 'upon the chains 26 I provide a tension device in the form of an idler or pinion 41 carried by a bracket 42 which is pivotally secured to, the standard or supporting arm 23 and may be secured in any desired angular relation to the said supporting arm or standard so as to carry the adjacent run of the chain 26 closer to or farther from the supporting arm, as will be readily understood.

The bed 1 of my improved carriage may be of any desired dimensions but should be sufficiently long to provide a proper support for the cultivator or other ground treating implements and the arches of the axles should be sufficiently high to. clear the plants. While I have contemplated the use of the carriagemore particularly in connection with cultivators as indicated by dotted lines in Fig. 1, it will'be understood that plows, barrows or other machines may be connected with the bed of the carriage so as to be drawn over the field thereby. It will be readily noted that the rear axle, which receives the thrust of the driving power and also is required to sustain the greater portion of all shocks to which the carriage is subjected'during its travel, is rigidly secured and the propelling force is applied at both ends thereof so that the machine will be propelled readily and will travel steadily. The standards or supporting bars connecting the rear axle with the counter shaft serve to brace both the axle and the counter shaft against torsional strain and the liability of the operating parts to get out of order is minimized.

A tool box 13 is illustrated upon the front end of the bed 1 and it will be understood of course that the-unoccupied space upon the bed may be utilized to transport extra sprocket wheels or other parts or may be otherwise employed.

Having thus described my invention, what I claim isi 1. In an apparatus for the purpose set forth, the combination of a bed, an axle secured to the rear end of the aid bed, traction wheels upon said axle, supporting bars fitted to the ends of the axle and rising therefrom, a counter shaft journaled in the upper ends of said bars, intermediate bearings for said counter shaft. upon the bed, gearing connecting the counter shaft with the traction Wheels, and means upon the bed for rotating the counter shaft.

In an apparatus for the purpose set forth, the combination with a bed, a counter shaft thereon, an axle secured to the rear end of the bed, traction wheels on the said axle, gearing connecting the counter shaft with the said traction Wheels, and compris ing a pinion loosely mounted upon the coun ter shaft, a clutch member fitted upon the counter shaft ad acent said pinion, a

spring coiled around the counter shaft and bearin upon said clutch member to hold it norma ly in engagement with said pinion, a lever engaging said clutch member, said lever being fulcrumed in advance of said clutch member, a hand lever fulcrumed upon the bed and extending rearwardly therefrom, and a link connecting said hand lever with the rear end of the first-mentioned lever.

In testimony whereof I affix my signature in presence of two Witnesses.
